Front end noise.

[xplor3r]

I have a front end noise that sounds like almost like a light metal on metal sound. Its a tinny, slightly rattling sound. It goes away when i accelerate, returns right after i let off the gas. If I coast for a while maybe 10 seconds the noise eventually goes away. I thought maybe the brakes, but when i tap the brakes it doesnt effect the sound at all. Any ideas?

Rattles can come from many things...lol If it does it at idle then craw up under and listen for the noise, have someone give it a little gas if it helps identify the noise easier.
First rattles that come to mind are:
Heat shield on Y-pipe
Heat shield on cat
Dust shield on back side of front rotors

I'd start there, and look/bang on everything you can think of while your down there checking. Good luck

Easiest way I can say to identify a heat shield rattle is to watch the RPMs and see if it happens in a certain range. I know my Cat Shield rattled at 2500-2800 no matter how fast, slow, or idle. A shield strap from autozone fixed the issue right up....so would a removal for that matter.
